For a number of years I have used a separate antivirus (AVG), antispyware (Spysweeper), and firewall (Zonealarm) without any problems. The antivirus and antispyware both run in realtime. I was looking into switching to Avira's antivirus, but the folks there told me that I shouldn't have more than one product doing realtime scanning because if there is a detection they could conflict. That would mean I have to pick between running the antivirus, or antispyware in real time but not both. That seems to me like inadequate protection. Is it really a problem to run both an antivirus and an antispyware at the same time? I realize that the lines between these products are getting blurrier each day. But it seems like the only "approved" solution would be to run a full internet suite from just one company. I was trying to avoid that as none of the suites seem to test as well as the various standalone products.
